The weakly bound 1:1 complex between acrylonitrile (CH2═CHCN) and water has been characterized spectroscopically in the millimeter wave range (59.6-74.4 GHz) using a Free Jet Absorption Millimeter Wave spectrometer. Precise values of rotational quartic centrifugal distortion constants have obtained from measured frequencies normal isotopically substituted moiety (DOH, DOD, H(18)OH). Structural parameters estimated their differences among isotopologues: planar structure with two subunits held...
In order to facilitate its detection in astronomical observations, the measurement of rotational spectrum acrylic acid has been extended 397 GHz using a free space cell at room temperature. 295 new lines were assigned s-cis conformer and 286 s-trans acid. Using determined experimental parameters, predictions transition frequencies up 900 their intensities obtained temperatures 100 200 K Based on these predictions, search most intense transitions star-forming regions was performed published...
The hydrogen-bonded complex between acrylonitrile (CH2═CHCN) and methanol has been characterized spectroscopically in the millimeter wave range (59.6–74.4 GHz) using a free jet absorption spectrometer. Precise values of rotational centrifugal distortion constants were obtained from measured frequencies with CH3OH CD3OD. analysis splittings lines due to hindered internal rotation methyl group led determination V3 value 221.9(7) 218(5) cm–1 for complexes CD3OD, respectively, these are about...
